Mitigation of oxygen decline in fjords by freshwater injection
Aksnes, Dag Lorents; Berntsen, Jarle Peder; Darelius, Elin Maria K. (Journal article; Peer reviewed, 2023)The exchange of water masses between deep fjords and the open ocean is commonly constrained by a topographical barrier called the sill. While fjord water above the sill depth communicates relatively freely with the open ... -
Modelling secondary circulations in stratified bi-directional flows: A potential mechanism for flux transfer from lower to upper fluid layers
Grifoll, Manel; Berntsen, Jarle Peder; Cuthbertson, Alan (Journal article; Peer reviewed, 2023)Results are presented for new laboratory-scale numerical simulations of bi-directional stratified flows generated within an idealized trapezoidal sill-channel topography, focussing on the lateral (or secondary) flow structure ... -
Rotational effects on exchange flows across a submerged sill
Cuthbertson, A.; Berntsen, Jarle Peder; Laanearu, J.; Asplin, Magdeli (Journal article; Peer reviewed, 2021)This paper presents new laboratory-scale numerical simulations of density-driven exchange flows generated across an idealised, submerged sill obstruction under both non-rotating and rotating frames of reference using the ... -
Topographic effects on buoyancy driven flows along the slope
Berntsen, Jarle Peder; Chiche, Elin Maria Kristina Darelius; Avlesen, Helge (Journal article; Peer reviewed, 2022)The flow and descent of dense water masses formed in shallow regions of the ocean is an important leg in the global overturning circulation. The dense overflow waters tend to flow along the continental slopes as geostrophically ...
